DeepSeek 4.1
Large language model from DeepSeek, version 4.1, used via chat and API.
Commenters use it as a daily driver, including for frontend and backend code,123 and like it as a cheap model that hallucinates less than 4.0 and costs far less than a Claude subscription.45 The main caveat is that one daily user calls it nowhere close to top models,6 and it ranks low on at least one benchmark.7
